METHOD FOR OPTIMIZATION OF SYNCHRONIZATION BETWEEN A CLIENT'S DATABASE AND A SERVER DATABASE

摘要

A method and system for synchronizing a first database with a second database is disclosed. A client containing a first version of a database transmits a first synchronization message from the client to the server. The message contains MAPITEM records from a previous synchronization process, UPDATES for the present synchronization process, a current synchronization time and a last synchronization time. A second version of the database within a server is updated responsive to the first synchronization message. The server transmits a second synchronization message to the client containing UPDATES to be performed at the client, the RESULTS of the updates requested by the client, and the received current synchronization time from the first synchronization message. The client updates the first database, removes the previously transmitted MAPITEMs and stores the MAPITEM records for the present synchronization process for transmission during a next synchronization process.
